Former Hamilton and Partick Thistle goalkeeper Tomas Cerny has left Aberdeen and retired from football due to an ongoing knee problem.
The 35-year-old Czech has been at Pittodrie since the summer of 2018, making just one start as back-up to Dons captain Joe Lewis.
With Cerny injured, Gary Woods was signed on loan in October but has now returned to Oldham Athletic.
"The club needs a goalkeeper now," Cerny told the club website.
"My career comes to an end. It is not the way I planned it, but my knee injury means I'm not able to take part in regular training and matches."
Cerny, who plans to remain in Scotland and train as a PE teacher, added: "I'd have liked to play a few more games for Aberdeen, but it is credit to Joe Lewis, he has been terrific, very consistent and producing great performances week in, week out."
